In 8-quart saucepot, heat white and sweet potatoes and enough water to cover to boiling. Reduce heat to low; cover and simmer 25 minutes or until potatoes are almost tender but still firm when pierced with a fork. (Check sweet potatoes after 20 minutes as they cook faster than white potatoes.) Drain potatoes; set aside until cool enough to handle.

Meanwhile, thinly slice cabbage and onion; set aside. In 5-quart Dutch oven or saucepot over medium-high heat, cook sausage until golden brown, stirring frequently. With slotted spoon, spoon sausage into a small bowl. Discard all but 2 tablespoons fat from sausage in Dutch oven.
